benzimidazole, quinazoline, and imidazopyridine is reported using hypervalent iodine as the key reagent. Acetoxy, aryl, iodide and nitro functional groups were introduced on the same substrate by simply shifting the reaction conditions in the presence of inorganic additives (Cs2CO3, I2, NaNO2) and the hypervalent iodine reagent (diacetoxyiodo)benzene (PIDA) underaerobicconditions. The combination
